I learnt these words from Brandy Leary of Anandam Dancetheatre, she learnt them from Aimée Dawn Robinson. Aimée's latest work can be found here. I think these words are very important:
"We wish to acknowledge the traditional territories of the Anishnaabe, the Mississauga’s of the New Credit, the Haudenosaunee, the Huron-Wendat, the Cree and any other Nations who cared for the land (acknowledged or unacknowledged, recorded or unrecorded). Thank you for hosting this performance on your land."
